Entry-Level Job Hunt in Investment Analysis: A Frustrating Journey

I completed my MBA a year ago and have been actively pursuing roles in Investment Analysis. Unfortunately, most positions require prior experience, which I lack. However, I firmly believe that I possess the necessary skills for this role. Despite numerous applications, securing an entry-level position in Investment Banking (IB) has been challenging. I am seeking guidance on how to identify opportunities, particularly within startup environments, where I can demonstrate my capabilities. If anyone has insights or opportunities within their firm, especially in London, I would greatly appreciate the assistance. Thank you.
